GNGTS 2018 S essione 3.2 637 variations of these tectonized carbonate breccias, with respect to their electrical and seismic characteristics and better define the stress-field-orientations. Finally, the fracturing and kinematic analysis on fault planes observed along trenches, highlighted systems of left and right-lateral transtensional faults, NW-SE, NNW-SSE and NE- SW trending respectively, which antedate the extensional tectonic event. The reconstructed stress-field-orientation related to the last tectonic system does not comply with the active stress field for this sector of the Sicilian chain. Moreover all the tectonic structures are sealed by Upper Pleistocene – Holocene continental deposits. Acknowledgements. The authorswish to thankDr.Antonino Pisciotta for the opportunity to use the photogrammetric survey. This research was carried out in the frame of the agreement with RAP S.p.A stipulated for the geological and geophysical study of the dumping of Bellolampo (Palermo, Italy).
